The Lady Bird Johnson Wildflower Center Fauna Project |
Our beautiful autumn weather continues as this survey was completed by five volunteers under foggy then cool, breezy and sunny conditions. The Twig Girdler, shown below, is a longhorn beetle that provides a dead wood food source for its young by killing the outer tips of tree branches before laying eggs in them. The mother beetle accomplishes this by chewing a deep groove all the way around the twig. She chooses where to cut by "measuring" the branch's width with her legs and never cuts deep enough to completely sever the branch, although it may later snap off at the weakened point.
